Representative young woman stops before she should, left out (8)
I believe the answer is:
emissary
'representative' is the definition.
(emissary is a kind of representative)
'young woman stops before she should left out' is the wordplay.
I cannot really understand how this works, but
'young' could be 'y' and 'y' is located in the answer.
'woman' could be 'em' and 'em' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for emissary that I've seen before include "one dispatched officially" , "Delegate" , "Agent sent on a mission" , "Person sent on a diplomatic mission" , "Diplomatic messenger" .)
